Win7 + Tuneup utilities (use the trial than kick it out). make a profile in tuneup (look at the top. theres a option to make a profile) & it'll automatically give a lot of suggestions. check which you think is good, discard the rest. in the end, Win7 will run as fast as XP, if not faster. i have done it on a old P4 desktop. so it should be same for your netbook. do try once.
